How to check if there is macromedia flash player installed on browser?

Question

I am using uploadify plugin to upload images. On some browsers uploadify button is not shown because of unavailability of macromedia flash player, I guess.

Is there any way to check if there is macromedia flash player installed, If not then show a link to download flash player at the place of upload button.

Thanks
